The floristic elements of woody plants was computed and the results indicate that the elements of Tropical Asia accounts for the largest number of genus while the proportion of the elements of Temperate Asia is relatively small. For each of eight vegetation region, the number of woody plants was established and a list of the endangered and rare species was compiled. In regard to the problems of protecting the endangered precious and rare species at present we propose some workable solutions.展开更多
